Fig. 3. Effects of peptone (0.1%) and phage (PR04-1) on growth of exponential phase Salmonella cells in worst case water microcosms (± SE, n = 4). (A) Peptone effect without phage. (B) Peptone effect with phage. (C) Phage effect with peptone. (D) Phage effect without peptone. Symbols: closed diamond (
), +phage + peptone; open diamond (
), +phage–peptone; closed square (
),–phage +peptone; open square (
),–phage–peptone.
